Help me choose a mosfet

Recommended Posts

Hi,I have an application where I have to switch on/off 2 3.3V low powerdevices(~50mA max combined) with a 3.3V MCU signal. I am currentlyusing a TP0610K that I have lying around with the followingconnections.Source - 3.3VGate - 50K pullup to 3.3V, and MCU control signalDrain - 1M pulldown and device Vcc

There are a few more, but I just want to make sure if I have the rightidea. Basically what I'm thinking is that I need a mosfet that has thefollowing characteristics:1) low threshold voltage(all the above have Vgs(th) >= -1V2) Sufficient Id(-120mA and less should be sufficient?)3) Low Rds(on)(single digit, or even <1ohm shouldn't cause anynoticable voltage dip at device Vcc)

Some of the above mosfets are for logic rather than power switching,but I'm guessing that as long as the current capacity(Id) issufficient, it shouldn't matter?

Thanks, but due to the existing design I have to use a P channel transistor. Is a low RDS and Vth all that I should be looking at? I guess I just need to know some guidelines on what parameters are important when choosing a transistor. I might even go for a PNP BJT since they seem to be more recommended.
